Next Audi R8 to eschew engine downsizing, go on diet instead

Looking across the Audi landscape, many models that used to get the company's high-revving, naturally aspirated 4.2-liter V8 are now powered by smaller, yet similarly powerful, forced-induction engines. From what Auto Express is reporting, though, the next-generation Audi R8 will not meet this same fate.
Rather than ditching its V8 and V10 powerplants, the next-gen R8 - expected to debut in 2015 - will shed pounds from its curb weight. The 2014 R8 currently weighs between 3,583 pounds and up to 3,957 pounds, but the report says that engineers are targeting a weight of less than 3,300 pounds. All models will get cylinder deactivation, which along with lower curb weights should help to improve fuel economy and emissions. Head on over to Auto Express for more reported information as well as a handful of renderings that take a stab at how the next R8 may look.

Audi is working on a suspension that gets power from bumpy roads

Regenerative brakes aren't new. They're on virtually every hybrid and EV, and they're even starting to pop up on traditional gas-powered cars, like with the i-ELOOP-equipped Mazda6. But even with these systems, cars can get more efficient, and Audi thinks it found yet another source of wasted energy. The source? The suspension. The idea is to turn the kinetic energy that goes into the dampers into usable energy instead of as waste heat. Audi isn't the first auto company to come up with regenerative suspension – nearly three years ago, ZF introduced its GenShock technology, which used a valve attached to traditional, oil-filled hydraulic shocks to recapture kinetic energy from movement caused by bumps in the road. Audi's prototype technology, which it calls eROT, replaces traditional dampers with horizontally oriented electromechanical rotary dampers. eROT is apparently short for electromechanical rotary damper. Neat. In testing, eROT recovered an average of 100 to 150 watts on a typical German road, three watts from a fresh piece of pavement, and 613 watts on a rough stretch of tarmac (wattage is calculated as power over time, so this is actually the rate at which the system harvests energy). The dampers channel that energy to a tiny, 0.5-kWh, 48-volt battery. The prototype is claimed to cut CO2 emissions by three grams per kilometer (4.8 grams per mile), while the company believes a future production version could save up to 0.7 liters of fuel per 100 kilometers of driving. Converting the savings to American miles per gallon isn't easy, so we'll use a practical example. In the US, the Q7's supercharged 3.0-liter V6 returns a combined rating of 21 miles per gallon, which works out to 11.2 liters per 100 kilometers. Apply eROT's 0.7L/100km savings, and the Q7's economy would improve to 10.5L/100km, or 22.4 mpg, a 1.4-mpg improvement. That's not huge, but because math, 0.7L/100km is more dramatic on a more fuel efficient vehicle – taking an A3's 27-mpg combined rating and adding eROT would drive efficiency up 2.4 mpg, for example. There are a few other big benefits beyond fuel and emissions savings – Audi claims eROT provides a more comfortable ride than traditional active suspensions, because engineers can tune the compression and rebound strokes independently of each other. Beyond that, the horizontally oriented rear suspension geometry means more cargo space, since the dampers don't poke up into the cabin like they normally do.

VW CEO talks up 20 new plug-in models in Frankfurt

For years now, Volkswagen has dreamed big, forming plans to become the world's largest automaker. That trajectory includes a big plug-in vehicle push, and the CEO of Volkswagen, Martin Winterkorn, said that his group of companies will bring out 20 more EVs and plug-in hybrids by 2020. The list includes the next Phaeton and the Audi A8. "No commitment to electro-mobility can be any clearer than that," Winterkorn said, according to a VW press release. "Our Group already has the largest connected vehicle fleet on the road. By 2020 we will have transformed all of our new cars into smartphones on wheels." Perhaps most illustrative, Winterkorn admitted that the auto industry has turned a corner. "Technological leadership is no longer solely defined in terms of horsepower and torque," he said. "We are taking the precision, enduring value and quality of our cars into the new, digital world." The VW group is also showing off new plug-in concepts in Frankfurt this week, like the Tiguan GTE and the Porsche Mission E. Winterkorn's prepared remarks do not give out the details of these vehicles, but we'll have all the info from the show floor in short order. Stay tuned. PROF. DR. MARTIN WINTERKORN: "THE REINVENTION OF VOLKSWAGEN" 14/09/15 from Volkswagen Group 20 more electric cars and plug-in hybrids by 2020 announced Group not only has broadest electric fleet, but also largest connected vehicle fleet on the road Customers should benefit from automated driving technologies as quickly as possible Volkswagen taking precision, enduring value and quality of its cars into the digital world Wolfsburg/Frankfurt am Main, September 14, 2015 – In the Volkswagen Group, there is a sense that a new era is dawning. On the eve of the 66th International Motor Show (IAA) in Frankfurt am Main the CEO of Volkswagen Aktiengesellschaft, Prof. Dr. Martin Winterkorn, said on Monday evening: "We are in the process of reinventing Europe's largest automaker, laying the technological, economic and structural foundations." The Group Chairman announced there would be 20 more electric cars and plug-in hybrids by 2020 – from compact cars to the next Phaeton and Audi A8: "No commitment to electro-mobility can be any clearer than that." He said the Group already had the broadest electric fleet in the automobile world, and added that Volkswagen was also at the forefront when it came to the future-oriented field of digitisation: "Our Group already has the largest connected vehicle fleet on the road.
